Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582106, here are decompositions:

13 + 31582093 = 31582106
79 + 31582027 = 31582106
103 + 31582003 = 31582106
109 + 31581997 = 31582106
223 + 31581883 = 31582106
229 + 31581877 = 31582106
313 + 31581793 = 31582106
397 + 31581709 = 31582106

Showing the first eight; more decompositions exist.
